- Such a resiliently supported displacement or force-bound forming machine is well known in the art.
- such machines can be designed for pressure forming, tension pressure forming, tension forming, bending forming or shear forming.
- away-bound forming machines such as away-bound presses
- the path of the ram device (bear) is through the Kinematics of the drive of the machine fixed. It is usually driven by an electric motor which drives a flywheel which can be connected to the ram device by coupling it in order to initiate the working stroke.
